CLAIM OF PRIORITY

The present application claims the benefit of priority to U.S. Provisional Patent Application Ser. No. 61/287,759, filed on Dec. 18, 2009, entitled Carriage of JPEG 2000 Part 1 Video Over MPEG-2 Transport Streams, by Mandayam A. Narasimhan, the disclosure of which is hereby incorporated by reference in its entirety.

BACKGROUND

Communication networks are often the medium through which digital content distributors transmit protected content. Communications protocols and content formatting standards have been developed which standardize how certain types of protected content are conveyed over various types of communication network architectures. However, new technologies are emerging with respect to the communications systems used, the content formatting standards applicable with new types of content, and the network architectures which may be utilized by the distributing and/or receiving parties of the protected content.

Given the ongoing changes in the technologies used in distributing and viewing protected content, currently available protocols and standards are often not adequate or operable for attaining acceptable interoperability among systems using different protocols or content formatted according to different standards. Furthermore, as new protocols for communication networks and/or new standards for new content formats are implemented to accommodate changes in technology, existing protocols or standard may not be adequate to fully or even partially implement the changes in technology.

In the case of video-based protected content, especially those which rely on high efficiency compression methods to enable transport through communications networks, the need for interoperability among new technologies, new protocols and new standards is especially high. This is partly due to the wide variety of technical options constantly being developed for packaging video-based protected content for distribution. It is also due to the wide variety of usage options being developed and deployed for the end consumers of video-based protected content.

DETAILED DESCRIPTION OF EMBODIMENTS

For simplicity and illustrative purposes, the principles of the embodiments are described by referring mainly to examples thereof. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the embodiments. It is apparent however, to one of ordinary skill in the art, that the embodiments may be practiced without limitation to these specific details. In some instances, well known methods and structures have not been described in detail so as not to unnecessarily obscure the embodiments. Furthermore, different embodiments are described below. The embodiments may be used or performed together in different combinations.

1. Content Distribution System

In a content distribution system (CDS), such as the CDS 100 illustrated in FIG. 1A, a content distribution facility, such as a headend 101, may be used to package and distribute protected content, such as video-based content. The video-based content may be packaged and transmitted, for example, via an MPEG-2 transport stream 102. The MPEG-2 transport stream 102 may include a plurality of video and audio streams associated with different data formats and programs provided through the CDS 100 to various types of client premises equipment (CPE) and client devices such as, for example, a cell phone 103, a set-top box 104 and a computer 105. Other CPEs and client devices may include multimedia devices (e.g., digital cameras, personal digital assistants, mobile phones, color facsimile, printers, scanners, etc).

The MPEG-2 transport stream includes different types of packetized information as illustrated in FIG. 1B. FIG. 1B shows an MPEG-2 transport stream cut out 150 of the MPEG-2 transport stream 102 shown in FIG. 1A. The MPEG-2 transport stream 102 may include a PES which are the video packets 170 a to 170 d and the program information packet 160, according to an embodiment. The program information packet 160 includes control information to reference one or a plurality of video packets, such as video packets 170 a to 170 d. The program information packet 160 includes control information, such a program map table 161 including a J2K video descriptor 162 to reference the video packets 170 a to 170 d. The J2K video descriptor 162 includes information describing what types of J2K video data, such as J2K video data 173 a, may be included in a video packet, such as video packet 170 a, and how the J2K video data is used, such as use in a still picture, a slide show or as frames of video in a J2K video sequence used in a program specified within the program map table 161. In another embodiment, a PES may include only video packets which may be referenced by control information, such as the information in the J2K video descriptor 162, which is not located in a program information packet associated with a PES in a transport stream but is instead located elsewhere in the transport stream including the PES.

The video packets in the PES illustrated in FIG. 1B include video packets 170 a to 170 d. Video packet 170 a is representative of the other video packets 170 b to 170 d. It includes a J2K video access unit 171 a. The J2K video access unit 171 a includes an ELSM header 172 a and J2K video data 173 a, such as encoded J2K image data for a single a frame, such as a J2K still picture or a frame in a J2K video sequence.

The program information packet 160 includes control information for managing and/or using the video packets 170 a to 170 d. The program information packet 160 associated with video packet 170 a includes a program map table 161 which includes the J2K video descriptor 162. The information in the J2K video descriptor 162 is used to direct usage of the J2K access unit 171 a in the J2K video packet 170 a. The video packets 170 a to 170 d may be included in a video PES which is multiplexed with other elementary streams and program streams in the MPEG-2 transport stream 102.

The J2K video access unit 171 a includes encoded J2K video data 173 a and an ELSM header 172 a. The J2K video data 173 a in the J2K access unit 171 a, before it is encoded, may be referred to as J2K image data. The J2K image data encoded in the J2K video access unit 171 a may be associated with a single frame or a still picture of J2K image data. A J2K video access unit, such as J2K video access unit 171 a, is a unit of encoded J2K image data for a complete frame in a video or a still picture. The J2K video access unit 171 a also includes parameters in the ELSM header 172 a which may be used to decode the J2K access unit 171 a and to display the decoded J2K image data. The information in the J2K video descriptor 162 and the ELSM header 172 a both reference the J2K video data 173 a, but in different ways. In comparison with the information in the J2K video descriptor 162, the ELSM header 172 a in the J2K access unit 171 contains relatively low level video-centric data for decoding and displaying the video data 173 a as decoded J2K image data. As noted above, the information in the J2K video descriptor 162 is used to direct usage of the J2K access unit 171 a in the J2K video packet 170 a. This is a higher level referencing than in the ELSM header 172 a. However, the J2K video descriptor 162 may include some of the same metadata parameters and information included in the ELSM header 172 a about the J2K video data 173 a. Thus, the J2K video descriptor 162 enables a higher level access to some of the information in the ELSM header 172 a, without accessing all of the information about the J2K video data 173 a included in the ELSM header 172 a.

The MPEG-2 transport stream 102 including video packets, such as video packets 170 a to 170 d including J2K video access units, may be used in client/server communications (e.g., the Internet, Image database, video streaming, video server, etc.) distributing cinema and for the exchange of content as well as the contribution of content to service providers. It may also be used in entertainment services and over broadband services utilizing satellites, cable system, 3DTV systems and IPTV systems. The MPEG-2 transport stream 102 including J2K video access units, such as J2K video access unit 171 a, may also be used in satellite imaging systems, medical imaging systems, systems for high-quality frame-based video recording, editing and storage, digital cinema systems, high quality video (2D and 3DTV) contribution systems to distribution points and systems used for imaging weather or astronomical recording.

2. Encoding and Decoding Systems

FIG. 2 illustrates the encoding system 210 and the decoding system 240, according to an embodiment. The decoding system 240 is representative of any of the CPEs or client devices discussed above with respect to FIG. 1A. In FIG. 2, there is block diagram illustrating an encoding system 210 delivering the MPEG-2 transport stream 102 to the decoding system 240, according to an embodiment. The encoding system 210 includes a controller 211, a counter 212, a frame memory 213, an encoding unit 214 and a transmitter buffer 215. The decoding system 240 includes a receiver buffer 250, a decoding unit 251, a frame memory 252 and a controller 253. The encoding system 210 and the decoding system 240 are coupled to each other via a transmission path including the MPEG-2 transport stream 102. The controller 211 of the encoding system 210 controls the amount of data to be transmitted on the basis of the capacity of the receiver buffer 250 and may include other parameters such as the amount of data per a unit of time. The controller 211 controls the encoding unit 214, to prevent the occurrence of a failure of a received signal decoding operation of the decoding system 240. The controller 211 may include, for example, a microcomputer having a processor, a random access memory and a read only memory.

An incoming signal 220 supplied from, for example, a video camera recording J2K digital images, which are input to the frame memory 213. The frame memory 213 has a first area used for storing the incoming signal 220 from the video camera, and a second area used for reading out the stored signal and outputting it to the encoding unit 214. The controller 211 outputs an area switching control signal 223 to the frame memory 213. The area switching control signal 223 indicates whether the first area or the second area is to be used.

The controller 211 outputs an encoding control signal 224 to the encoding unit 214. The encoding control signal 224 causes the encoding unit 214 to start an encoding operation. In response to the encoding control signal 224 from the controller 211, including control information such as the information referenced in the J2K video descriptor 162 and/or the ELSM header 172 a, the encoding unit 214 starts to read out the video signal to a high-efficiency encoding process, such as an interframe coding process or a discrete cosine transform to encode the J2K image data to form J2K video access units. Each J2K video access unit, such a J2K access unit 171 a, includes an ELSM header, such a ELSM header 172 a. A ELSM header generally includes metadata about a J2K access unit which is used to assist in decoding and displaying the J2K image data in from encoded J2K video data. According to an embodiment, the control signal includes the J2K video descriptor information and may include other video metadata parameters. As described above, the J2K video descriptor includes information associated with the J2K video access unit. It may also include information associated with a J2K video sequence, a J2K still picture or both.

A table containing metadata fields in an exemplary J2K video descriptor is demonstrated in Table I below.

TABLE I No. Of Table I - J2K Video Descriptor Syntax bits Mnemonic J2K_video_descriptor( ) {   descriptor_tag 8 uimsbf   descriptor_length 8 uimsbf   profile_and_level 16 uimsbf   horizontal_size 32 uimsbf   vertical_size 32 uimsbf   max_bit_rate 32 uimsbf   max_buffer_size 32 uimsbf   DEN_frame_rate 16 uimsbf   NUM_frame_rate 16 uimsbf   color_specification 8 bslbf   still_mode 1 bslbf   interlaced_video 1 bslbf   reserved 6 bslbf   private_data_byte 8 bslbf

The fields in the exemplary J2K video descriptor of Table I are now described for illustrative purposes.

Profile_and_Level may be coded to indicate broadcast profile and level values associated with the J2K access unit and the video sequence that are part of the program. These parameters are defined in the J2K video standard and are also included in the J2K video descriptor as this is the interoperability point between encoding system 210 and the decoding system 240. For example—a decoder that cannot support a particular profile and level will not attempt to decode the J2K video access unit.

Horizontal_size may be coded to correspond with a horizontal size parameter in a J2K codestream (ELSM) header for a code stream in the J2K video access unit.

Vertical_size may be coded to correspond with a vertical size parameter in a J2K codestream (ELSM) header for a code stream in the J2K video access unit.

Max_bit_rate may be coded to express the maximum compressed bit rate value for the profile and level specified.

Max_buffer_size may be coded to express the maximum buffer size value for the profile and level specified.

DEN_frame_rate and NUM_frame_rate are fields for coding a J2K frame rate derived from the DEN_frame_rate and NUM_frame_rate values.

The encoding unit 214 prepares an encoded video signal 222 in a packetized elementary stream (PES) including video packets 160 and program information packets 170. The encoding unit 214 maps the video access units into video packets 160 using a program time stamp (PTS) and the control information. The PTS and the control information are also associated with the program information packet 170 which is associated with a corresponding video packet 160. The encoded video signal 222 is stored in the transmitter buffer 214 and the information amount counter 212 is incremented to indicate the amount of data in the transmitted buffer 215. As data is retrieved and removed from the buffer, the counter 212 is decremented to reflect the amount of data in the buffer. The occupied area information signal 226 is transmitted to the counter 212 to indicate whether data from the encoding unit 214 has been added or removed from the transmitted buffer 215 so the counter 212 can be incremented or decremented. The controller 211 controls the production of packets produced by the encoding unit 214 on the basis of the occupied area information 226 communicated in order to prevent an overflow or underflow from taking place in the transmitter buffer 215.

The information amount counter 212 is reset in response to a preset signal 228 generated and output by the controller 211. After the information counter 212 is reset, it counts data output by the encoding unit 214 and obtains the amount of information which has been generated. Then, the information amount counter 212 supplies the controller 211 with an information amount signal 229 representative of the obtained amount of information. The controller 211 controls the encoding unit 214 so that there is no overflow at the transmitter buffer 215.

The receiver buffer 250 of the decoding system 240 may temporarily store the PES with encoded data received from the encoding system 210 via the MPEG-2 transport stream 102. The decoding system 240 counts the number of frames of the received data, and outputs a frame number signal 263 which is applied to the controller 253. The controller 253 supervises the counted number of frames at a predetermined interval, for instance, each time the decoding unit 251 completes the decoding operation.

When the frame number signal 263 indicates the receiver buffer 250 is at a predetermined capacity, the controller 253 outputs a decoding start signal 264 to the decoding unit 251. When the frame number signal 263 indicates the receiver buffer 250 is at less than a predetermined capacity, the controller 253 waits for the occurrence of the situation in which the counted number of frames becomes equal to the predetermined amount. When the frame number signal 263 indicates the receiver buffer 250 is at the predetermined capacity, the controller 253 outputs the decoding start signal 264. The video access units are decoded in a monotonic order (i.e., increasing or decreasing) based on a presentation time stamp (PTS) in the header of the program information packets 170 and the ELSM header 151 of the video packets 160 associated with corresponding program information packets 170.

In response to the decoding start signal 264, the decoding unit 251 decodes data amounting to one frame from the receiver buffer 250, and outputs the data. The decoding unit 251 writes a decoded video signal 262 into the frame memory 252. The frame memory 252 has a first area into which the decoded video signal is written, and a second area used for reading out the decoded video data and outputting it to a monitor or the like.

3. Methods

FIG. 3A illustrates a method 300 according to embodiment, for encoding J2K video data in a PES in MPEG-2 transport stream 102. The PES may be a J2K video elementary stream including J2K video access units in video packets. The method is described with respect to the encoding system 210 shown in FIG. 2 by way of example and not limitation. The method may be performed in other systems. The steps of the methods may be performed in a different sequence or one or more may be omitted.

At step 301, the encoding system 210 receives an incoming signal 220 including frames of J2K image data as well as metadata such as control information to generate other parameters for transport. These parameters may include interleaving or mixing program information packets and video packets, described further below with respect to step 304.

At step 302, the encoding system 210 encodes the frames of J2K image data to form J2K video access units. Each J2K video access unit includes an ELSM header. The MPEG-2 transport stream also includes a program information packet with a J2K video descriptor with video metadata parameters that may also be included in the ELSM header. The J2K video descriptor also includes other parameters that are needed to convey information about the video sequence and application usages. The J2K video descriptor includes information, such as described in table 1 above, associated with the J2K video access unit and either a video sequence or a still picture. The J2K video access unit also includes a PES header including timing reference information, including the PTS, which identifies a time associated with the encoding and/or decoding of the J2K video access unit. Also, the J2K video access unit includes one or more codestreams associated with a frame of the J2K image data. A codestream is a bit stream data associated with the frame of image data in the J2K video access unit.

At step 303, the encoding system 210 maps the J2K video access units into PES packets using the PTS in the PES header of the J2K video access units.

At step 304, the encoding system 210 creates the video packets which may be mixed with program information packets and then orders these packets as PES packets in a monotonic order using the PTS in the PES packets to form a PES. The PES may be incorporated into the MPEG-2 transport stream 102 using a multiplexer.

FIG. 3B illustrates a method 350 according to embodiment, for decoding video data in a PES. The decoding method is described with respect to the decoding system 240 shown in FIG. 2 by way of example and not limitation. The method may be performed in other systems.

At step 351, the decoding system 240 receives the PES in a receiver buffer 250 and extracts the video packets and the program information packets. The video packets in the PES includes the J2K image data in J2K video access units. Each J2K video access unit includes an ELSM header and the MPEG-2 transport stream also includes program information packets including the J2K video descriptor including the control information including video metadata parameters associated with application specific functions including the image data such as display, slide shows, etc. The J2K video descriptor may also include information in common with the ELSM header associated with the J2K video access unit relating to the J2K video data as being a video sequence, a still picture or both. The PES headers for the video packets also includes timing reference information including a PTS, and one or more codestreams associated with a frame of the image data.

At step 352, the decoding system 240 retrieves each J2K video access units present in the buffer in a monotonic order associated with the PTS in the PES header of the J2K video access unit.

At step 353, the decoding system 240 decodes the removed J2K video access units to form a signal including the decoded J2K image data.
